Hi,
I have a quick question about the 767 accumulator pressure gauge.
Does this gauge actually measure pressure of the inert gas pressure in the accumulator instead of of hydraulic pressure itself?
I understand that the accumulator will normally indicate about 3000 psi when the normal or alternate brakes (R&C hydraulics) are operative and the accumulator contains inert gas, as normal. In the absence of R or C hydraulic pressure, it will indicate accumulator inert gas pressure.
Is it true to say: If there is a problem and the accumulator leaks its gas, the accumulator gauge could read 0 yet the normal or alternate brakes are still functioning normally? When might it read 0? Only during brake application, or would it read 0 continuously if the accumulator leaked its gas?
Also, it's my understanding that anti-skid is only available for normal and alternate brakes. Is this correct? It would seem that reserve and accumulator breaking would be using the same brake lines, and might still have anti-skid, but the manual says otherwise.
Thanks.
